Hi, I am seeing the following error in my logs: Caused by: java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key com.arjuna.ats.internal.jta.transaction.arjunacore.syncwhenaborted I've found this mentioned in the (closed) jira issue: http://jira.jboss.com/jira/browse/JBTM-231 But this is for Jboss TS, so I'm not clear if this is something that is fixed in AS 4.2.1.GA (I am currently using 4.2.0.GA), or if there is another change I can make; e.g. just replcae jboss-transaction.jar? cheers phil View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082408#...
